Application filed May 20, 1915. Serial No. 29,298.

To all u. ham. it in try concern. f

Be it known that I MERTON H. GRnnsoN a citizen of the United States, and a resident of Tampa, in the county of Hillsboro and State ofFlorida, have invented certain new and useful Improvements in Flush- Siphons, of which the following is a specification.

dy present invention relates generally to flush siphons, and more particularly to a siphon for flushing tanks, one object among others being to provide a rigid non-movable siphon whereby to eliminate the usual siphon seat and rubber gasket utilized in the ordinary lift siphon now in use and to promote a non-leaking structure resulting in the prolongation of the life of the usual ball cock washers and the elimination of practically all repairs.

A further object of my invention is to provide a flush siphon including simple, novel, and effective means for inducing siphonage,

With these and other objects in mind, my invention specifically resides in the features to be now described in connection with the accompanying drawing, which forms a part of this specification, and in which:

Figure 1 is a vertical longitudinal section through a flush tank provided with my improvement, taken substantially on line l1 ofl ig. 2, and Fig. 2 is a vertical cross section taken therethrough substantially on line 2 2 of Fig. 1.

Referring now to these figures, I have shown a conventional flush tank at A, in which my invention is disposed, and it will be noted that my improved siphon is of inverted U-shape, one extension B carrying the lower spud 72 by which the siphon is rigidly attached through the base of the tank A as clearly shown through the use of a lock nut C, the other extension terminating in an open lower inlet end 6 within the tank A and slightly above the base thereof.

The last mentioned extension B of the siphon is preferably cast integral with a box D, one side wall and the base of which are curved on an arc of which the shaft E is the center, this shaft being journaled through openings at the sides of the upper opening of the box top D and carrying a rigid and preferably integral paddle E within the box, this paddle normally assuming the horizontal position at the upper open end of the box D shown in Fig. 1, due to the weight of its exterior connections as hereinafter described. Thus the normal position of the paddle permits of the rise of water in the tank A which finds itsway through an opening in the opposite wall of the box D, such opening being shownat D- and nor mally covered by an inwardly opening valve plate F hingedly connected at its upper end F.

To the outer end of the shaft E is rigidly and preferably integrally attached, a crank arm E united by apivotal upright link G, with an actuating arm or lever H, through actuation of which the crank arm E may be raised from the lower position it normally assumes, as shown in Fig. 1, to force the starting paddle E downwardly within the box D and induce siphonage through the tube B, B. Thus, the box D, being integral and therefore rigid with the siphon tube B, B, the usual siphon seat and rubber gasket are done away with and the number of necessary moving parts reduced to minimum. Furthermore, by thus eliminating leakage in the siphon, the life of the ball cock washer will be materially prolonged and repairs practically eliminated.

By the use of a siphon so constructed, the siphonage is readily and easily induced, by simple and inexpensive means, the whole producing a highly satisfactory and durable siphon which may be easily and quickly installed, and which may be made in various sizes and shapes to conform with the many styles of siphon tanks now in use.

I claim 1- 1. A siphon comprising a siphon tube, an inlet box into which the inlet end of the siphon tube opens, having one wall and its base arcuately curved, and having an inlet opening through another wall, a plate hinged within the box to cover its said open ing and moving inwardly therefrom, a shaft journaled across the upper portion of the casing and provided at one end with an ex ternal crank, and a starting paddle carried by the shaft and disposed and movable within the box to force fluid therefrom through the inlet of the siphon tube, and connections to the said shaft crank for oscillating the shaft.

2. A siphon comprising an inverted U- shaped siphon tube, the inlet extension of which terminates short of the outlet extension, an attaching spud carried by the out- 7 minates short of the outlet extension, an inlet box rigidly connected to and surrounding thesaid inlet extension and having an inwardly opening valve at one side, a shaft journaled across the casing, a starting paddle carried by the shaft and movable Within the casing to force the liquid into the inlet extension of the siphon tube, and connections for oscillating the said shaft.
